Inflation with a quadratic potential occurs naturally in theories where an axion-like field mixes with a 4-form. Such an axion is massive, with the mass which arises from the mixing being protected by the axion shift symmetry. The 4-form backgrounds...

We give a full list of known N=1 supersymmetric quantum field theories related by the Seiberg duality conjectures for the SU(N), SP(2N) and G_2 gauge groups. There are both new dualities and new theories with confinement, not considered earlier in...
